Abstract
A transparent layered element includes two outer layers that each have a smooth outer main surface and are constituted of dielectric materials having substantially the same refractive index. The layered element also includes a central layer inserted between the outer layers. The central layer is formed either by one or more layers made of metallic material or made of dielectric material having a refractive index different from that of the outer layers. All of the contact surfaces between two adjacent layers of the layered element are textured and parallel to one another. A ratio of a total reflection of the layered element on a side of a first outer layer in a given wavelength range to a total reflection of the layered element on a side of a second outer layer in the given wavelength range is greater than or equal to 1.5.
